The present invention relates to handled bags, and more particularly, relates to single use, food service, sealable bags with integrated venting.
Conventional lunch bag-shaped paper bags have been in use in the food industry since at least the commencement of take-out fast food services. These upper open ended paper bags are easy to open, fill and close, providing simple access to its contents.
More recently, handled paper and plastic bags are becoming more commonly used in food delivery. While the use of these handled paper and plastic bags continues to proliferate in the food service industry, especially with the recent growth of third party food delivery services, the potential for food tampering also increases. Both the food preparer/provider and the consumer would like assurance the food prepared has not in any manner been touched or tampered prior to the delivery, as well as assure the consumer that they received the proper delivery without having to immediately open the sealed delivery bag.
Accordingly, it is desirable to provide a single use, handled paper or plastic delivery bag that is capable of being sealed in a manner that enables the end consumer assurance that the handled bag has not been opened, and that the prepared food therein has not been tampered with. It is also desirable to provide a sealed bag assembly that enables a note, such as a purchase receipt, order ticket, pick ticket, etc., to be easily attached to the sealed bag assembly for simple viewing of the order information such as the order number, consumer identification, order contents, purchase price, date and time, etc.
The present invention provides a tamper evident delivery bag assembly comprising a sheet-like first panel, an opposed sheet-like second panel, and a bottom gusset. Each the first and second panel includes an interior surface that faces the opposing panel and an exterior surface, and each panel further includes a respective upper section terminating at an upper first edge of the first panel and an opposed upper second edge of the second panel. The first and second edges cooperate to at least partially define a bag opening into a content receiving region extending between the bag opening, the panels and the bottom gusset. The upper sections are movable between an opened condition and a closed condition, the closed condition where the first and second edges generally oriented in opposed, adjacent, relationship to one another.
The present inventive delivery bag assembly further includes a single use closure tape member laterally mounted to the first panel upper section, and includes an upper lateral portion extending laterally above the first edge thereof in an unsealed condition. An adhesive is disposed on an interior surface of the tape upper lateral portion facing the second panels when in the unsealed condition. A removable protective strip is provided that covers the adhesive to maintain the tape in the unsealed condition until sealing is required. Hence, when the protective strip is removed, and the panel upper sections are aligned in the closed condition, the tape upper lateral portion can be folded over the second edge of the second panel such that the adhesive is brought into contact with the exterior surface of the second panel, substantially sealing the bag opening in a sealed condition.
In accordance with the present invention, the closure tape member further includes a note tab extending downwardly from the middle lateral portion. The note tab includes a tab adhesive disposed on an interior surface thereof facing the exterior surface of the first panel. A removable protective cover is disposed over the tab adhesive, in an unmounted condition, preventing unintentional adherence of the note tab to the exterior surface of the first panel. When the protective cover is removed, a note can be placed between the tab adhesive of the note tab and the exterior surface of the first panel, and adhered therebetween in a mounted condition.
Accordingly, by additionally adhering the note to the sealed bag assembly, bag contents and delivery destination can be easily identified, especially if the bag assembly has already been sealed.
In one specific embodiment, the lateral dimension of the note tab is in the range of about ¼ to about ⅓ the lateral length of the middle lateral portion of the closure tape member.
In another configuration, the note tab is positioned along one of the left side, the middle and the right side of the middle lateral portion of the closure tape member.
In another embodiment, a vertical dimension of the note tab extending downwardly from a lower edge of the middle lateral portion is in the range of about ¼ inch to about 1½ inch.
In still another specific embodiment, the note tab includes a tab cutout configured to facilitate the ease of removal of the protective cover. The tab cutout, in one example, is positioned at a lower corner of the note tab.
Yet another configuration provides the delivery bag assembly with a first handle mounted to the upper section of the first panel having a pair spaced-apart first leg portions upstanding from the first edge. Further, a second handle is mounted to the upper section of the second panel having a pair spaced-apart second leg portions upstanding from the second edge The first and second handles together with the first and second leg portions are generally aligned adjacent one another and collectively define a gripping passage therethrough when the upper sections are oriented in the closed condition. The tape upper lateral portion includes a pair of handle cutouts strategically aligned with the leg portions of the first handle such that when the tape upper lateral portion is folded over the second edge of the second panel in the sealed condition, the leg portions of the first and second handles are received through the respective handle cutouts of the tape member.
In one specific embodiment, the tape upper lateral portion defines a middle closure section having a closure height extending vertically from the first edge to an upper edge of the middle closure section. The closure height is less than a vertical height of the gripping passage such that when the tape upper lateral portion is folded over the second edge of the second panel to the sealed condition, the middle closure section passes unobstructedly under the aligned handle members and through the gripping passage.
Another configuration provides the tape upper lateral portion that defines a first outer closure section and a second outer closure section on opposed sides of the middle closure section. At least one of the first outer closure section and the second outer closure section defines a closure cutout configured to facilitate the ease of removal of the protective strip.
In one embodiment, the bag assembly is comprised of one of paper material and plastic material.
In still another specific configuration, the tape member includes a plurality of elongated scoring slits extending in a direction substantially transverse to the respective first and second edge of the respective first and second panel and across the bag opening when the upper sections are in the closed condition and the tape member is in the sealed.
In another aspect of the present invention, a tamper evident method for delivering one or more food containers in a bag assembly that is configured to mount a note thereon. The method includes providing a handled delivery bag assembly having a sheet-like first panel, and an opposed sheet-like second panel, each the first and second panel having an interior surface that faces the opposing panel and an exterior surface Further, each panel further includes a respective upper section terminating at an upper first edge of the first panel and an opposed upper second edge of the second panel. The first and second edges cooperate to at least partially define a bag opening into a content receiving region extending between the bag opening and the first and second panels. The upper sections are movable between an opened condition and a closed condition. The bag assembly further includes a single use closure tape member laterally mounted to the first panel upper section at a middle lateral portion thereof, and having an upper lateral portion extending laterally above the first edge thereof in an unsealed condition. The closure tape member further including a note tab extending downwardly from the middle lateral portion in an unmounted condition. The method further includes reorienting the upper sections of the bag assembly to the opened condition to enable receipt of the one or more food containers in the content receiving region, and repositioning the upper sections of the bag assembly from the opened condition to the closed condition, orienting the first and second edges generally in opposed, adjacent, relationship to one another. The method includes exposing a closure adhesive disposed on an interior surface of the tape upper lateral portion facing the second panel when in the unsealed condition, and subsequently, folding the tape upper lateral portion over the second edge of the second panel such that the adhesive is brought into contact with the exterior surface of the second panel, substantially sealing the bag opening in a sealed condition. In accordance with the present invention, the method further includes exposing a tab adhesive disposed on an interior surface of the note tab facing the exterior surface of the first panel. Next, the method includes placing the note between the exposed tab adhesive of the note tab and the exterior surface of the first panel; and adhering the note therebetween in a mounted condition.
In one specific embodiment, the exposing the closure adhesive includes removing a protective strip from the closure adhesive; and the exposing the tab adhesive includes removing a protective cover from the tab adhesive.
Another embodiment includes the bag assembly having a first handle mounted to the upper section of the first panel having a pair spaced-apart first leg portions upstanding from the first edge, and a second handle mounted to the upper section second panel having a pair spaced-apart second leg portions upstanding from the second edge. The first and second handles together with the first and second leg portions are generally aligned adjacent one another and collectively defining a gripping passage therethrough when the upper sections are oriented in the closed condition. The tape upper lateral portion define a pair of handle cutouts strategically aligned with the leg portions of the first handle, wherein, the folding the tape upper lateral portion includes receiving the leg portions of the first and second handles through the respective handle cutouts of the tape member.
In yet another embodiment, the tape upper portion defining a middle closure section having a closure height extending vertically from the first edge to an upper edge of the middle closure section, the closure height being less than a vertical height of the gripping passage. The folding the tape upper lateral portion includes passing the middle closure section unobstructedly under the aligned handle members and through the gripping passage toward the sealed condition.
The assembly of the present invention has other objects and features of advantage which will be more readily apparent from the following description of the best mode of carrying out the invention and the appended claims, when taken in conjunction with the accompanying drawings, in which:
While the present invention will be described with reference to a few specific embodiments, the description is illustrative of the invention and is not to be construed as limiting the invention. Various modifications to the present invention can be made to the preferred embodiments by those skilled in the art without departing from the true spirit and scope of the invention as defined by the appended claims. It will be noted here that for a better understanding, like components are designated by like reference numerals throughout the various figures.
Turning now to
Accordingly, a single-use, tamper evident delivery bag assembly is provided that can be one-time sealed in a manner that will exhibit visible signs of tampering and destruction should someone attempt to access its contents, yet provides venting of the contents simply by the positioning of the closure adhesive and seal in such a manner to create venting. This single-use bag assembly is particularly useful in the food delivery service industry since the size of the vent or vents, while providing venting of steam for example, is sufficiently small so that delivery personal cannot tamper with the bag contents without tearing of the bag or seal.
In accordance with the present invention, the delivery bag assembly 20 includes a fairly conventional handled bag assembly with the sheet-like first panel 21 and the opposed sheet-like second panel 22 either directly joined at the opposed panel side edges 44, 47 and 48, 49, forming common opposed side seams (not shown) or joined at respective panel side edges by an opposed pair of sheet-like, vertically creased, side gussets 23, 25 therebetween. The folded sheet-like bottom gusset 26 is coupled to the bottom edges of the first and second panels 21, 22, and the bottom edges of the opposed side gussets 23, 25. The respective interior surfaces of the first and second panels 21, 22, the side gussets 23, 25, and the bottom gusset 26 collectively define the content receiving region. Moreover, the pair of opposed handles 27, 28 are preferably provided by conventional twisted loop handles, flat plastic or paper folded handles (
Briefly, it will be appreciated that while the present invention is particularly suitable for conventional handled paper bags, this tamper evident seal assembly can be applied to plastic bags as well as any other conventional bag materials utilized in the food delivery industry. Moreover, while the present invention is shown with bag assemblies with two handles, one mounted to each panel, it will be appreciated that the present invention applies to bag assemblies with only a single handle (e.g., only a single handle 27 mounted to the first panel 21, and no second handle 28 mounted to the second panel 22).
Referring now to
The remaining upper lateral portion of the tape member 30 is configured to be folded over the opposing second edge 32 of the second panel 22 (
Referring now to
It will be appreciated that the handle cutouts 45, 46 can be any shape, but must be sufficiently dimensioned to accommodate the lower leg portions 40-43 of the handles 27, 28 when the panel upper sections are oriented in the closed condition and the tape member is in the sealed condition. Moreover, it will be understood that integral cutout vent apertures 60, 61 into the bag interior are formed by the cutouts themselves when the tape member seals the bag opening (
Further, the outer vent apertures 62-65 are formed by the spacing between the outer distal edges of the outer closure section 50, 52 of the tape member 30 and the corresponding opposed side edges of the first and second panels 21, 22, as the tape member extends across roughly about 90% the width of the first and second panels. In this manner, when the outer closure sections 50, 52 of the tape member are sealed against the exterior surface of the second panel 22, the distal ends of the tape member 30 and the end creases of the corresponding folded side gussets 23, 25 form these four outer vent apertures 62-65. In contrast when the opposed side edges 44, 47 and 48, 49 of the panels 21, 22 are directly joined at side seams (not shown) whereby the upper side gussets are eliminated, only two outer vent apertures are formed between the outer distal edges of the tape outer closure section 50, 52 and the corresponding joined side edges of the panels.
Collectively, these vent apertures provide venting of contents sealed within the bag interior. This will of course assures proper steam venting of hot food content therein, for instance, when the bag assembly is being carried by the handles 27, 28. It will be appreciated, however, that each vent aperture or passage is of a lateral dimension sufficiently large to enable adequate venting of steam therethrough while being sufficiently small to prevent the passage of a human hand therethrough. These vent apertures are preferably in the range of opening to at least about 3.2 mm in diameter to no more than about 25.4 mm in diameter, and more preferably about 12.7 in diameter.
When the tape member 30 is folded over, using the adhesive 38 to seal off the bag opening, the bag assembly is temporarily closed while retaining the container contents in the content receiving region. The adhesive 38 of the tape member will maintain the closure of the bag assembly until forcibly opened and/or torn. Accordingly, a tamper evident seal is created, assuring both the food preparer/provider, the food delivery driver, and the customer that content contained in the bag assembly 20 has not been tampered with.
The character and properties of the adhesive of the closure tape member 30 is preferably similar to that of the relatively strong adhesives and adhesive tapes employed for those used on overnight delivery packages, for instance. That is, the adhesive strength must be sufficiently strong so that any attempt to open the sealed bag assembly would show visible signs of tampering (e.g., stretching, tearing, etc. of the bag material and/or closure adhesive). Suitable closure adhesive tape materials include, for example, 3M® 9086, 9888T, CT6348, 9088, 9088FL, and 55256 double-sided adhesive.
To prevent inadvertent closure or contact of the adhesive 38 of the remaining upper lateral portion of the tape member 30, as mentioned, the tape member 30 includes a manually removable protective strip 33 (
In accordance with the present invention, a single unit protective strip 33 is applied, spanning the voids created by the handle cutouts 45, 46 of the upper lateral portion of the tape member. In this manner, the protective strip can be removed as one unit rather than removing three separate units. This significantly reduces the time and effort required to remove the protective strip during sealing the bag assembly 20.
In one configuration, the tape member 30 includes strategic cuts or scoring 70 (e.g.,
In another aspect of the present invention, the tape member 30, alone, may be provided for mounting of the lower lateral portion of the tape member to the upper section 36 of the first panel 21 (
In still another aspect of the present invention, a method is provided for tamper evident delivering of one or more food containers in a handled bag assembly 20. The method includes providing a handled delivery bag assembly 20 having a sheet-like first panel 21, and an opposed sheet-like second panel 22. Each the first and second panel includes an interior surface that faces the opposing panel and an exterior surface. Each panel 21, 22 further includes a respective upper section 36, 37 terminating at an upper first edge 31 of the first panel and an opposed upper second edge 32 of the second panel. The first and second edges 31, 32 cooperate to at least partially define a bag opening 35 into a content receiving region extending between the bag opening and the first and second panels 21, 22. The upper sections 36, 37 are movable between an opened condition (
In one specific embodiment of this aspect of the present invention, the exposing the closure adhesive 38 includes removing a protective strip 33 from the closure adhesive.
In another aspect of the present invention, as shown in
In yet another aspect of the present invention, tape member 30 includes a note tab 73 oriented on the side opposite the upper lateral portion which is configured to secure a note 74 (
Accordingly, turning now to
As best shown in
The underside of the note tab 73 includes the tab adhesive 79 (
The width of the note tab 73 is generally in the range of about ⅓ of the width of the middle lateral portion 75 of the tape member (as well as the first panel 21 width). This note tab width is variable, of course, and may even extend laterally across the entire width of the middle lateral portion 75, although this is perhaps not practical. The note tab width, however, must be wider than the note 74 itself since if note tab were too narrow, a wider note may span the entire width of the tab adhesive, preventing or impairing the ability of adhering the note tab to the exterior surface of the first panel 21. Accordingly, the width of the note tab is preferably at least in the range of about 1″ to about 4″.
Similarly, the height of the note tab can vary in any length, although too shallow of a height will render the tab unusable since it may be too difficult to position and adhere the note between the tab adhesive and first panel 21. On the other hand, a note tab 73 that is too tall in height is impractical to use, and wasteful of paper resources. Accordingly, the height of the note tab 73 is preferably in the range of about ¼″ to about 1½″.
For the most part, only one note tab 73 is be incorporated (
Similar to the closure sections, the note tab or tabs can include respective tab cutouts 82-85 that effectively promote gripping of the protective cover 76 by providing an increased gripping surface area to enable easier removal of the cover. These tab cutouts are preferably oriented at the corners of the note tab or tabs, but can be at the center thereof as well. (
In another specific configuration (
